Best Video cable for picture quality?

Abstract7, The sony 9000 dvd player has audio RCA outputs
and a seperate RCA for video out. I will be running the
audio outputs directly into my audio system...so I am wanting to get the best cable for taking the video only
signal from the DVD player into the Sony XBR ..that has
inputs for Video and L & R Audio. Thanks

Actually on the back of the Sony 9000 there is also a "S"
and a set of component outputs. I can e-mail anyone a picture of the back of the unit..if it helps.

Slightly off topic, but I'd like to improve the quality of the signal I'm getting from the wall into my digital cable box. This is 75 ohm coax I believe and I'm not sure what they call the connector they use (short, thin, stiff wire). Benefits to upgrading this cable? Recommendations?

I recently bought a pair of used Monster M2000SV silver series S-VHS cables from "Underwoodwally" (one of the partners of the Perpetual Technologies products). He still has some of these cables left for about half-price -- look for his ads here on Audiogon. The M2000SV series is the best that Monster Cable makes, and they have been highly recommended in several video mags.

Drubin: a good quality low loss wideband 75 ohm RF coax is RG-6, available from Radio Shaft etc. along with type-F connectors. I have not evaluated any other coax's regarding differences in picture quality, but I expect the lowest loss cable is the one that yields best video performance. Anyone else?
